Definitions
- the present invention relates to oilfield tubulars and to threaded connection between two oilfield tubulars. More particularly, the invention relates to a threaded oilfield tubular connection with two shoulders.
- Oilfield tubular members such as drill-pipe
- the tube section may be upset and tool joints with a smaller ID welded to the ends of the tube section.
- it is desirable to form an entire joint from an integral bar for economic and material availability reasons, but since one end has to be a box end for receiving the pin end of another joint, the threaded connection is not able to have a “double shoulder” which provides increased torsional strength.
- the oilfield connection includes a box on one end of a tubular and a pin on the other end of the tubular, with mated threads joining the tubulars.
- a double shoulder connection may be used to retrofit previously manufactured drill string members to provide the double shouldered connection.
- a further feature of the invention is that the double shoulder connection may be provided on both the box end and the pin end of the connection, with one sleeve provided in the box and another sleeve provided on the pin.
- tubular member may be manufactured with two different IDs at its ends: a smaller ID for the pin and a larger ID for the remaining entire length of the joint, including the box.
- the sleeve may be made from either a similar or a dissimilar material as the corresponding pin or box.
- the sleeve may be retained in the box with one of an interference fit, a tapered fit, a threaded connection, or a weldment.
- the ID of the sleeve preferably approximates the ID of the pin.
- FIG. 1 is a conventional pin and box connection with mated threads.
- FIG. 2 illustrates a double shoulder pin and box connection according to one embodiment of the invention.
- FIG. 3 illustrates a pin provided with a sleeve.
- FIG. 4 illustrates a spiral upset section along a drill pipe.
- FIG. 5 is a cross-sectional view of the spiral upset shown in FIG. 4 .
- FIG. 6 illustrates the box end, with one-quarter cutaway, and the full sleeve in the box, as shown in FIG. 2 .
- FIG. 7 illustrates an interference fit connection
- FIG. 8 illustrates a welded connection
- FIG. 1 shows a conventional box end 10 and a pin end 12 with mated threads 14 . Only a single shoulder 16 is provided. According to the present invention, the same box 10 as shown in FIG. 1 may be provided with an inner sleeve 18 , which engages the box at shoulder 20 , thereby providing the double shoulders 16 , 22 . Each shoulder preferably lies substantially within a plane perpendicular to a central axis of the connection.
- the drill string member may be initially manufactured with two different IDs at its ends, a smaller ID for the pin 12 , and a larger ID for the entire remaining length of the joint, including the box 10 .
- Sleeve 18 may be made of a similar or dissimilar material, and may be retained in the box 10 by various techniques, including an interference fit, including a tapered interference fit, a threaded retention, or welding.
- FIG. 2 illustrates the sleeve 18 secured to the box 10 by threads 19 spaced axially between thread 14 and shoulder 20 .
- the cylindrical outer surface 21 on the sleeve 18 below the shoulder 20 may have a slight interference fit with the mating cylindrical shoulder of the box.
- the ID of the sleeve 18 preferably approximates the ID of the pin 12 , which the OD of the sleeve 18 provides for retention and absorption of loads.
- the box sleeve 18 may be formed from a dissimilar material from that used to fabricate the box end 10 , so that the desired characteristics of the box may be met by the selected material for forming a box 10 , while the desired characteristics for the sleeve 18 may be met by selecting a different material for the sleeve.
- an internal diameter of the box sleeve 18 approximates the internal diameter of the pin 12 .
- each of the first shoulder 16 and the second shoulder 22 has a substantial radial thickness compared to radial thickness of the oilfield connection, so that both shoulder 16 , 22 are able to carry a significant portion of the axial load transmitted through the connection.
- the radial thickness of the shoulder 16 and the radial thickness of the shoulder 22 are each at least 25% of the radial thickness of the oilfield connection. Accordingly, if the radial thickness between the outer cylindrical surface 52 of the connection as shown in FIG. 2 and the inner cylindrical surface 54 of the pin 12 is approximately 1.6 inches, then the radial thickness of each of the shoulders 16 , 22 is preferable at least 0.4 inches, and in many applications, one or both of the shoulders 16 , 22 may be about 30% or more of the radial thickness of the connection.
- the sleeve 18 as shown in FIG. 2 may be applied by retrofitting drill string members previously manufactured without a double shoulder connection. Also, this same concept may be employed on both the box and pin ends of the connection, in which case the box may be provided with the sleeve 18 as shown in FIG. 2, and the pin bore provided with a similarly shaped sleeve 24 , as shown in FIG. 3 . More particularly, sleeve 24 engages the pin 12 at shoulder 28 . Sleeve 24 may be similarly secured to the pin by threads 27 , with outer cylindrical surface 29 engaging the mating cylindrical surface of the pin.
- Table A provides characteristics for high performance drill pipe in several sizes according to the present invention, listing dimensions for both the tube and the drill joint.
- FIG. 4 illustrates pictorially a spiral upset connection 42 , which may be spaced along the one or both of the joints connected by the double shoulder connection discussed above.
- FIG. 5 is a cross-section of the spiral upset connection.
- FIG. 6 illustrates the box and sleeve generally shown in FIG. 2 .
